    27:48 If anyone wants to know why- O is more electronegative than C, so it pulls the bond e- towards itself and the Cs connected to Os gain partial positive charge. So, the Cs connected to these Cs gain partial negetive charge. Using this concept we can see that the middle C has more negetive character for being connected to 2 C-/=O. That is why the H connected to it are more positive which makes it easier to remove them for tautomer formation.

Even Akash ke Teachers jaha pe ma parh raha hu waha pa unhona iss topic pe zada focus hi nahi karvaya or aaga chala gya . Mujhe lag raha tha ki ye to kafi easy hoga par aab lag raha ha ki aaj mana apna din ke 3 ghanta kafi aacha kaam ma lagaye. Thanks a lot sir .

    • @muskanmi941

      You are right but here weaker h bonding take place bcz the this carbon is attached on benzene ring which leads on polarization b/w c and h and creates a delta plus charge on h

    At @41:53 I guess the order should be D>C>A>B ... The reason for D and C is okay .... But in B there is conjugation along a EWG(phenyl) and ERG(methyl) so since the arrangement of the bond is not in favour so it will be formed least...whereas in A there is conjugation and only one ERG (methyl).....
